C# 2012, Part 3 of 4: Asynchronous Programming

In this course you’ll learn about what async is and how it’s different from traditional synchronous programming. You’ll also learn the benefits of async. Before going into the new async language features, you’ll see how the previous async models worked and have a better understanding for what the problems were. This will form a basis of appreciation for how easy the new C# async model is and what the benefits are for you. Next, you’ll see the fundamental mechanics of how an async method is defined. You’ll learn how to use the new async and await contextual keywords to perform async operations. You’ll learn about different types of return values and when you should use each. The course will also cover common techniques of managing async tasks either sequentially or in parallel. You’ll learn how to catch exceptions from async code and what type of code to write to ensure that you can catch exceptions. You’ll learn how to cancel one or more async operations in predictable ways. Further, you’ll see how progress reporting occurs and the ease in which you can integrate it with async methods.
